DESCRIPTION

Fexofenadine hydrochloride, the active ingredient of ALLEGRA, is a histamine H1-receptor antagonist with the chemical name (±)-4-[1 hydroxy-4-[4-(hydroxydiphenylmethyl)-1-piperidinyl]-butyl]-α,α-dimethyl
benzeneacetic acid hydrochloride. It has the following chemical structure

The molecular weight is 538.13 and the empirical formula is C32H39NO4•HCl.

Fexofenadine hydrochloride is a white to off-white crystalline powder. It is freely soluble in methanol and ethanol, slightly
soluble in chloroform and water, and insoluble in hexane. Fexofenadine hydrochloride is a racemate and exists as a zwitterion
in aqueous media at physiological pH.

ALLEGRA is formulated as a capsule or tablet for oral administration. Each capsule contains 60 mg fexofenadine hydrochloride
and the following excipients: croscarmellose sodium, gelatin, lactose, microcrystalline cellulose, and pregelatinized starch.
The printed capsule shell is made from gelatin, iron oxide, silicon dioxide, sodium lauryl sulfate, titanium dioxide, and
other ingredients.

CLINICAL PHARMACOLOGY

Mechanism of Action

Fexofenadine hydrochloride is an antihistamine with selective peripheral H1-receptor antagonist activity. Both enantiomers of fexofenadine hydrochloride displayed approximately equipotent antihistaminic
effects. Fexofenadine inhibited histamine release from peritoneal mast cells in rats. In laboratory animals, no anticholinergic,
alpha1-adrenergic or beta-adrenergic-receptor blocking effects were observed. No sedative or other central nervous system effects
were observed. Radiolabeled tissue distribution studies in rats indicated that fexofenadine does not cross the blood-brain
barrier.

Pharmacokinetics

Absorption

Fexofenadine hydrochloride was rapidly absorbed following oral administration of a single dose of two 60 mg capsules to healthy
male volunteers with a mean time to maximum plasma concentration occurring at 2.6 hours post-dose. After administration of
a single 60 mg capsule to healthy subjects, the mean maximum plasma concentration was 131 ng/mL. Following single dose oral
administrations of either the 60 and 180 mg tablet to healthy, adult male volunteers, mean maximum plasma concentrations were
142 and 494 ng/mL, respectively. The tablet formulations are bioequivalent to the capsule when administered at equal doses.
Fexofenadine hydrochloride pharmacokinetics are linear for oral doses up to a total daily dose of 240 mg (120 mg twice daily).
The administration of the 60 mg capsule contents mixed with applesauce did not have a significant effect on the pharmacokinetics
of fexofenadine in adults.

Distribution

Elimination

The mean elimination half-life of fexofenadine was 14.4 hours following administration of 60 mg, twice daily, in normal volunteers.

Human mass balance studies documented a recovery of approximately 80% and 11% of the [14C] fexofenadine hydrochloride dose in the feces and urine, respectively. Because the absolute bioavailability of fexofenadine
hydrochloride has not been established, it is unknown if the fecal component represents unabsorbed drug or the result of biliary
excretion.

Metabolism

Approximately 5% of the total oral dose was metabolized.

Special Populations

Special population pharmacokinetics (for geriatric subjects, renal and hepatic impairment), obtained after a single dose of
80 mg fexofenadine hydrochloride, were compared to those for normal subjects from a separate study of similar design. While
subject weights were relatively uniform between studies, these adult special population patients were substantially older
than the healthy, young volunteers. Thus, an age effect may be confounding the pharmacokinetic differences observed in some
of the special populations.

The pharmacokinetics of fexofenadine hydrochloride in seasonal allergic rhinitis and chronic idiopathic urticaria patients
were similar to those in healthy subjects.

Geriatric Subjects

In older subjects (≥65 years old), peak plasma levels of fexofenadine were 99% greater than those observed in normal volunteers
(<65 years old). Mean elimination half-lives were similar to those observed in normal volunteers.

Pediatric Patients

Cross study comparisons indicated that fexofenadine hydrochloride area under the curve (AUC) following oral administration
of a 60 mg dose to 7–12 year old pediatric allergic rhinitis patients was 56% greater compared to healthy adult subjects given
the same dose. Plasma exposure in pediatric patients given 30 mg fexofenadine hydrochloride is comparable to adults given
60 mg.

Renal Impairment

In patients with mild to moderate (creatinine clearance 41–80 mL/min) and severe (creatinine clearance 11–40 mL/min) renal
impairment, peak plasma levels of fexofenadine were 87% and 111% greater, respectively, and mean elimination half-lives were
59% and 72% longer, respectively, than observed in normal volunteers. Peak plasma levels in patients on dialysis (creatinine
clearance ≤10 mL/min) were 82% greater and half-life was 31% longer than observed in normal volunteers. Based on increases
in bioavailability and half-life, a dose of 60 mg once daily is recommended as the starting dose in patients with decreased
renal function. (See DOSAGE AND ADMINISTRATION).

Hepatic Impairment

The pharmacokinetics of fexofenadine hydrochloride in patients with hepatic disease did not differ substantially from that
observed in healthy patients.

Effect of Gender

Across several trials, no clinically significant gender-related differences were observed in the pharmacokinetics of fexofenadine
hydrochloride.

Pharmacodynamics

Wheal and Flare

Human histamine skin wheal and flare studies following single and twice daily doses of 20 and 40 mg fexofenadine hydrochloride
demonstrated that the drug exhibits an antihistamine effect by 1 hour, achieves maximum effect at 2 to 3 hours, and an effect
is still seen at 12 hours. There was no evidence of tolerance to these effects after 28 days of dosing.

Histamine skin wheal and flare studies in 7 to 12 year old patients showed that following a single dose of 30 or 60 mg, antihistamine
effect was observed at 1 hour and reached a maximum by 3 hours. Greater than 49% inhibition of wheal area, and 74% inhibition
of flare area were maintained for 8 hours following the 30 and 60 mg dose.

Effects on QTc

In dogs (30 mg/kg/orally twice a day), and in rabbits (10 mg/kg, infused intravenously over 1 hour) fexofenadine hydrochloride
did not prolong QTc. In dogs, the plasma fexofenadine concentration was approximately 9 times the therapeutic plasma concentrations in adults
receiving the maximum recommended daily oral dose. In rabbits, the plasma fexofenadine concentration was approximately 20
times the therapeutic plasma concentration in adults receiving the maximum recommended daily oral dose. No effect was observed
on calcium channel current, delayed potassium channel current, or action potential duration in guinea pig myocytes, sodium
current in rat neonatal myocytes, or on several delayed rectifier potassium channels cloned from human heart at concentrations
up to 1 × 10-5 M of fexofenadine hydrochloride.

No statistically significant increase in mean QTc interval compared to placebo was observed in 714 seasonal allergic rhinitis patients given fexofenadine hydrochloride capsules
in doses of 60 to 240 mg twice daily for two weeks. Pediatric patients from two placebo controlled trials (n=855) treated
with up to 60 mg fexofenadine hydrochloride twice daily demonstrated no significant treatment or dose-related increases in
QTc. In addition, no statistically significant increase in mean QTc interval compared to placebo was observed in 40 healthy volunteers given fexofenadine hydrochloride as an oral solution at
doses up to 400 mg twice daily for 6 days, or in 231 healthy volunteers given fexofenadine hydrochloride 240 mg once daily
for 1 year.

Clinical Studies

Seasonal Allergic Rhinitis

Adults

In three, 2-week, multicenter, randomized, double-blind, placebo-controlled trials in patients 12 to 68 years of age with
seasonal allergic rhinitis (n=1634), fexofenadine hydrochloride 60 mg twice daily significantly reduced total symptom scores
(the sum of the individual scores for sneezing, rhinorrhea, itchy nose/palate/throat, itchy/watery/red eyes) compared to placebo.
Statistically significant reductions in symptom scores were observed following the first 60 mg dose, with the effect maintained
throughout the 12-hour interval. In these studies, there was no additional reduction in total symptom scores with higher doses
of fexofenadine hydrochloride up to 240 mg twice daily.

In one 2-week, multicenter, randomized, double-blind clinical trial in patients 12 to 65 years of age with seasonal allergic
rhinitis (n=863), fexofenadine hydrochloride 180 mg once daily significantly reduced total symptom scores (the sum of the
individual scores for sneezing, rhinorrhea, itchy nose/palate/throat, itchy/watery/red eyes) compared to placebo. Although
the number of patients in some of the subgroups was small, there were no significant differences in the effect of fexofenadine
hydrochloride across subgroups of patients defined by gender, age, and race. Onset of action for reduction in total symptom
scores, excluding nasal congestion, was observed at 60 minutes compared to placebo following a single 60 mg fexofenadine hydrochloride
dose administered to patients with seasonal allergic rhinitis who were exposed to ragweed pollen in an environmental exposure
unit. In one clinical trial conducted with ALLEGRA 60 mg capsules, and in one clinical trial conducted with ALLEGRA-D extended
release tablets, onset of action was seen within 1 to 3 hours.

Pediatrics

Two 2-week multicenter, randomized, placebo-controlled, double-blind trials in 877 pediatric patients 6 to 11 years of age
with seasonal allergic rhinitis were conducted at doses of 15, 30, and 60 mg twice daily. In one of these two studies, conducted
in 411 pediatric patients, all three doses of fexofenadine hydrochloride significantly reduced total symptom scores (the sum
of the individual scores for sneezing, rhinorrhea, itchy nose/palate/throat, itchy/watery/red eyes) compared to placebo, however
a dose response relationship was not seen. The 60 mg twice daily dose did not provide any additional benefit over the 30 mg
twice daily dose. Furthermore, exposure in pediatric patients given 30 mg fexofenadine hydrochloride is comparable to adults
given 60 mg (see CLINICAL PHARMACOLOGY).

Three clinical safety studies in 845 children aged 6 months to 5 years with allergic rhinitis comparing 15 mg BID (n=85) and
30 mg BID (n=330) of an experimental formulation of fexofenadine to placebo (n=430) have been conducted. In general, fexofenadine
hydrochloride was well tolerated in these studies. No unexpected adverse events were seen given the known safety profile of
fexofenadine and likely adverse reactions for this patient population. (See PRECAUTIONS Pediatric Use and ADVERSE REACTIONS.)

Chronic Idiopathic Urticaria

Two 4-week multicenter, randomized, double-blind, placebo-controlled clinical trials compared four different doses of fexofenadine
hydrochloride tablet (20, 60, 120, and 240 mg twice daily) to placebo in patients aged 12 to 70 years with chronic idiopathic
urticaria (n=726). Efficacy was demonstrated by a significant reduction in mean pruritus scores (MPS), mean number of wheals
(MNW), and mean total symptom scores (MTSS, the sum of the MPS and MNW score). Although all four doses were significantly
superior to placebo, symptom reduction was greater and efficacy was maintained over the entire 4-week treatment period with
fexofenadine hydrochloride doses of ≥60 mg twice daily. However, no additional benefit of the 120 or 240 mg fexofenadine hydrochloride
twice daily dose was seen over the 60 mg twice daily dose in reducing symptom scores. There were no significant differences
in the effect of fexofenadine hydrochloride across subgroups of patients defined by gender, age, weight, and race.

INDICATIONS AND USAGE

Seasonal Allergic Rhinitis

ALLEGRA is indicated for the relief of symptoms associated with seasonal allergic rhinitis in adults and children 6 years
of age and older. Symptoms treated effectively were sneezing, rhinorrhea, itchy nose/palate/throat, itchy/watery/red eyes.

Chronic Idiopathic Urticaria

ALLEGRA is indicated for treatment of uncomplicated skin manifestations of chronic idiopathic urticaria in adults and children
6 years of age and older. It significantly reduces pruritus and the number of wheals.

CONTRAINDICATIONS

ALLEGRA is contraindicated in patients with known hypersensitivity to any of its ingredients.

PRECAUTIONS

Drug Interaction with Erythromycin and Ketoconazole

Fexofenadine hydrochloride has been shown to exhibit minimal (ca. 5%) metabolism. However, co–administration of fexofenadine
hydrochloride with ketoconazole and erythromycin led to increased plasma levels of fexofenadine hydrochloride. Fexofenadine
hydrochloride had no effect on the pharmacokinetics of erythromycin and ketoconazole. In two separate studies, fexofenadine
hydrochloride 120 mg twice daily (two times the recommended twice daily dose) was co-administered with erythromycin 500 mg
every 8 hours or ketoconazole 400 mg once daily under steady state conditions to normal, healthy volunteers (n=24, each study).
No differences in adverse events or QTc interval were observed when patients were administered fexofenadine hydrochloride alone or in combination with erythromycin
or ketoconazole. The findings of these studies are summarized in the following table:

Effects on steady-state fexofenadine hydrochloride pharmacokinetics after 7 days of co-administration with fexofenadine hydrochloride
120 mg every 12 hours (two times the recommended twice daily dose) in normal volunteers (n=24)

The changes in plasma levels were within the range of plasma levels achieved in adequate and well-controlled clinical trials.

The mechanism of these interactions has been evaluated in in vitro, in situ, and in vivo animal models. These studies indicate that ketoconazole or erythromycin co-administration enhances fexofenadine gastrointestinal
absorption. In vivo animal studies also suggest that in addition to increasing absorption, ketoconazole decreases fexofenadine hydrochloride
gastrointestinal secretion, while erythromycin may also decrease biliary excretion.

Drug Interactions with Antacids

Administration of 120 mg of fexofenadine hydrochloride (2 × 60 mg capsule) within 15 minutes of an aluminum and magnesium
containing antacid (Maalox®) decreased fexofenadine AUC by 41% and Cmax by 43%. ALLEGRA should not be taken closely in time with aluminum and magnesium containing antacids.

Carcinogenesis, Mutagenesis, Impairment of Fertility

The carcinogenic potential and reproductive toxicity of fexofenadine hydrochloride were assessed using terfenadine studies
with adequate fexofenadine hydrochloride exposure (based on plasma area-under-the-concentration vs. time [AUC] values). No
evidence of carcinogenicity was observed in an 18-month study in mice and in a 24-month study in rats at oral doses up to
150 mg/kg of terfenadine (which led to fexofenadine exposures that were respectively approximately 3 and 5 times the exposure
from the maximum recommended daily oral dose of fexofenadine hydrochloride in adults and children).

In rat fertility studies, dose-related reductions in implants and increases in postimplantation losses were observed at an
oral dose of 150 mg/kg of terfenadine (which led to fexofenadine hydrochloride exposures that were approximately 3 times the
exposure of the maximum recommended daily oral dose of fexofenadine hydrochloride in adults).

Pregnancy

Teratogenic Effects

Category C.

There was no evidence of teratogenicity in rats or rabbits at oral doses of terfenadine up to 300 mg/kg (which led to fexofenadine
exposures that were approximately 4 and 31 times, respectively, the exposure from the maximum recommended daily oral dose
of fexofenadine in adults).

There are no adequate and well controlled studies in pregnant women. Fexofenadine should be used during pregnancy only if
the potential benefit justifies the potential risk to the fetus.

Nonteratogenic Effects

Dose-related decreases in pup weight gain and survival were observed in rats exposed to an oral dose of 150 mg/kg of terfenadine
(approximately 3 times the maximum recommended daily oral dose of fexofenadine hydrochloride in adults based on comparison
of fexofenadine hydrochloride AUCs).

Nursing Mothers

There are no adequate and well-controlled studies in women during lactation. Because many drugs are excreted in human milk,
caution should be exercised when fexofenadine hydrochloride is administered to a nursing woman.

Pediatric Use

The recommended dose in patients 6 to 11 years of age is based on cross-study comparison of the pharmacokinetics of ALLEGRA
in adults and pediatric patients and on the safety profile of fexofenadine hydrochloride in both adult and pediatric patients
at doses equal to or higher than the recommended doses.

The safety of ALLEGRA tablets at a dose of 30 mg twice daily has been demonstrated in 438 pediatric patients 6 to 11 years
of age in two placebo-controlled 2-week seasonal allergic rhinitis trials. The safety of ALLEGRA for the treatment of chronic
idiopathic urticaria in patients 6 to 11 years of age is based on cross-study comparison of the pharmacokinetics of ALLEGRA
in adult and pediatric patients and on the safety profile of fexofenadine in both adult and pediatric patients at doses equal
to or higher than the recommended dose.

The effectiveness of ALLEGRA for the treatment of seasonal allergic rhinitis in patients 6 to 11 years of age was demonstrated
in one trial (n=411) in which ALLEGRA tablets 30 mg twice daily significantly reduced total symptom scores compared to placebo,
along with extrapolation of demonstrated efficacy in patients ages 12 years and above, and the pharmacokinetic comparisons
in adults and children. The effectiveness of ALLEGRA for the treatment of chronic idiopathic urticaria in patients 6 to 11
years of age is based on an extrapolation of the demonstrated efficacy of ALLEGRA in adults with this condition and the likelihood
that the disease course, pathophysiology and the drug's effect are substantially similar in children to that of adult patients.

Three clinical safety studies comparing 15 mg BID (n=85) and 30 mg BID (n=330) of an experimental formulation of fexofenadine
to placebo (n=430) have been conducted in pediatric patients aged 6 months to 5 years. In general, fexofenadine hydrochloride
was well tolerated in these studies. No unexpected adverse events were seen given the known safety profile of fexofenadine
and likely adverse reactions for this patient population. (See ADVERSE REACTIONS and CLINICAL PHARMACOLOGY.)

The safety and effectiveness of fexofenadine hydrochloride in pediatric patients under 6 years of age have not been established.

Geriatric Use

Clinical studies of ALLEGRA tablets and capsules did not include sufficient numbers of subjects aged 65 years and over to
determine whether this population responds differently from younger patients. Other reported clinical experience has not identified
differences in responses between the geriatric and younger patients. This drug is known to be substantially excreted by the
kidney, and the risk of toxic reactions to this drug may be greater in patients with impaired renal function. Because elderly
patients are more likely to have decreased renal function, care should be taken in dose selection, and may be useful to monitor
renal function. (See CLINICAL PHARMACOLOGY).

ADVERSE REACTIONS

Seasonal Allergic Rhinitis

Adults

In placebo-controlled seasonal allergic rhinitis clinical trials in patients 12 years of age and older, which included 2461
patients receiving fexofenadine hydrochloride capsules at doses of 20 mg to 240 mg twice daily, adverse events were similar
in fexofenadine hydrochloride and placebo-treated patients. All adverse events that were reported by greater than 1% of patients
who received the recommended daily dose of fexofenadine hydrochloride (60 mg capsules twice daily), and that were more common
with fexofenadine hydrochloride than placebo, are listed in Table 1.

In a placebo-controlled clinical study in the United States, which included 570 patients aged 12 years and older receiving
fexofenadine hydrochloride tablets at doses of 120 or 180 mg once daily, adverse events were similar in fexofenadine hydrochloride
and placebo-treated patients. Table 1 also lists adverse experiences that were reported by greater than 2% of patients treated
with fexofenadine hydrochloride tablets at doses of 180 mg once daily and that were more common with fexofenadine hydrochloride
than placebo.

The incidence of adverse events, including drowsiness, was not dose-related and was similar across subgroups defined by age,
gender, and race.

was well tolerated in these studies. No unexpected adverse events were seen given the known safety profile of fexofenadine
and likely adverse reactions for this patient population. (See PRECAUTIONS Pediatric Use.)

Chronic Idiopathic Urticaria

Adverse events reported by patients 12 years of age and older in placebo-controlled chronic idiopathic urticaria studies were
similar to those reported in placebo-controlled seasonal allergic rhinitis studies. In placebo-controlled chronic idiopathic
urticaria clinical trials, which included 726 patients 12 years of age and older receiving fexofenadine hydrochloride tablets
at doses of 20 to 240 mg twice daily, adverse events were similar in fexofenadine hydrochloride and placebo-treated patients.
Table 3 lists adverse experiences in patients aged 12 years and older which were reported by greater than 2% of patients treated
with fexofenadine hydrochloride 60 mg tablets twice daily in controlled clinical studies in the United States and Canada and
that were more common with fexofenadine hydrochloride than placebo. The safety of fexofenadine hydrochloride in the treatment
of chronic idiopathic urticaria in pediatric patients 6 to 11 years of age is based on the safety profile of fexofenadine
hydrochloride in adults and adolescent patients at doses equal to or higher than the recommended dose (see Pediatric Use).

surveillance include: insomnia, nervousness, and sleep disorders or paroniria. In rare cases, rash, urticaria, pruritus and
hypersensitivity reactions with manifestations such as angioedema, chest tightness, dyspnea, flushing and systemic anaphylaxis
have been reported.

OVERDOSAGE

Reports of fexofenadine hydrochloride overdose have been infrequent and contain limited information. However, dizziness, drowsiness,
and dry mouth have been reported. Single doses of fexofenadine hydrochloride up to 800 mg (six normal volunteers at this dose
level), and doses up to 690 mg twice daily for 1 month (three normal volunteers at this dose level) or 240 mg once daily for
1 year (234 normal volunteers at this dose level) were administered without the development of clinically significant adverse
events as compared to placebo.

In the event of overdose, consider standard measures to remove any unabsorbed drug. Symptomatic and supportive treatment is
recommended.

No deaths occurred at oral doses of fexofenadine hydrochloride up to 5000 mg/kg in mice (110 times the maximum recommended
daily oral dose in adults and 200 times the maximum recommended daily oral dose in children based on mg/m2) and up to 5000 mg/kg in rats (230 times the maximum recommended daily oral dose in adults and 400 times the maximum recommended
daily oral dose in children based on mg/m2). Additionally, no clinical signs of toxicity or gross pathological findings were observed. In dogs, no evidence of toxicity
was observed at oral doses up to 2000 mg/kg (300 times the maximum recommended daily oral dose in adults and 530 times the
maximum recommended daily oral dose in children based on mg/m2).
